9514 1404 393

Answer:

  $342.37

Step-by-step explanation:

When a quantity is marked up by x%, its marked-up price is (1 +x/100) times its original price. Tax is effectively a markup.

Louise's costs are ...

  $125 + (12.50 +19.50)(1.07) = $159.24

Louise priced her painting at ...

  $159.24·(1 +1.15) = $342.37

daser333 [38]

In this problem situation:

  • the independent quantity is <em><u>the money</u></em> Angela's grandfather gave her
  • the dependent quantity is the <em><u>number of raffle ticket</u></em> Angela will buy.

An independent quantity is the quantity that affects or brings a change in a dependent quantity.

The dependent quantity is affected by the independent quantity. If the independent quantity changes, the dependent quantity will change.

The dependent quantity is dependent on the independent quantity.

<em><u>Let's relate it to the </u></em><em><u>problem situation</u></em><em><u>:</u></em>

  • The amount of money Angela's grandfather gave her is unknown, therefore, the number of raffle tickets Angela can buy cannot be ascertain.

  • If we know <em>how much Angela's grandfather gave her</em>, we can determine <em>how many </em><em>raffle tickets </em>Angela can buy.

  • This implies that the number of raffle ticket Angela will buy is dependent on how much money her grandfather gave her.

Therefore, in this problem situation:

  • the independent quantity is <em><u>the money</u></em> Angela's grandfather gave her
  • the dependent quantity is the <em><u>number of raffle ticket</u></em> Angela will buy.

Find the inverse of the linear function y=1/2x+3.
Anni [7]

Answer:

2(x-3) = y

Step-by-step explanation:

y = 1/2 x +3

To find the inverse, exchange x and y and then solve for y

Exchange x and y

x = 1/2y +3

Then solve for 3

Subtract 3 from each side

x-3 = 1/2 y -3+3

x-3 = 1/2 y

Multiply each side by 2

2 (x-3) = 1/2 *2 y

2(x-3) = y

This is the inverse
